Which level 4 monster is the best?

I just don't understand what the difference is between a battle between two heroes or a hero against a monster?
P.S.: and this example proved that golems have a chance! albeit a small one, but they do!

Let me explain. You see, the computer places neutral troops based on the strength of the kingdom's army. If your power exceeds the opponent's (the creature standing on the ground), then this unit will contain only 1 stack; if, in terms of total health, you are still far behind the computer :) (sorry for the pun, it's just easier to express it this way in this situation), then its troops will be divided into 7 stacks, and this is usually what gives and takes away the advantage in battle. If the forces are equal, then the number of units on the battlefield will be somewhere around 3-4 stacks.

Regarding the example: I don't think you can calculate it that way..., the computer doesn't behave rationally (everyone knows that :)), but even if you just fly straight ahead, without waiting, it's enough to simply get into a corner..., not to mention using the terrain...

Sincerely.
